Abstract
The utility model relates to an all-electric living wheel-chair which has the technical characteristics that the utility model adopts rear three-point structure, and the drive and the turning are controlled in an all-electric mode. Two front wheels are free wheels and have a manual function, and a rear wheel performs driving and turning functions. The utility model is composed of a wheel-chair body, a manipulator, a drive device, a turning device, an all-electric control device, etc. The utility model can realize the advance, retreat, speed regulation and directional proportional control of the wheel-chair through the manipulator. The utility model has the advantages of dual purposes of electric driving and human power, novel design, flexible and convenient control and reliable operation, and is an ideal tool of riding instead of walk of limb disabled people, weak patients and old people.
Description
This utility model relates to a kind of people with disability of convenience and old people's all-electric life wheel Wheel-chair.
The patient of disabled people person and walking disorder, old people wish that oneself solves the walking problem, strengthen self care ability, thirst for having the convenient wheelchair that is suitable for.Use more hand-pushing wheel Wheel-chair now, need manual operation, walking is main to be realized by two wheels about two hand propelled of user, handle effort, use inconvenient, and on the market existing electric wheelchair remain at complex structure, cost an arm and a leg, shortcoming such as understeer work, working service inconvenience, use is restricted.Therefore, existing wheelchair can not satisfy disabled people person and weak patient, old human needs well.
The purpose of this utility model is that a kind of the driving with the life that turns to all-electric control of design taken turns Wheel-chair.
The purpose of this utility model is achieved in that with charging battery jar and dc motor be power, under the control of electric control system, is realized the driving of wheel Wheel-chair and the all-electric control that turns to by manipulator.This utility model mainly is made up of manipulator, car body, driving device, transfer, electric control system, charging battery jar, car body (12) adopts back bikini structure, two free front-wheels (13), double the turning to trailing wheel (15), two universal idle pulleys (14) and elevating mechanism (16) thereof of driving are housed on the car body (12), two free front-wheels (13) have manual function, trailing wheel (15) rises and drives and steering-effecting, and two universal idle pulleys (14) and elevating mechanism (16) thereof are in order to keep the human control function of wheel Wheel-chair.
Manipulator (11) is contained on the handrail of car body (12), the stick (21) of manipulator (11) but all around pass, after control signal is sent into the electric control system processing, driving device and transfer work in control trailing wheel (15), can make speed governing operation behind the wheelchair Herba Plantaginis, about turn to, operation is spinned in the original place.The speed of moving behind the angle ratio ground servo-actuated control wheelchair Herba Plantaginis of passing before and after the stick (21), the angle that turns to about the angle ratio of passing about stick (21) ground control wheel Wheel-chair.Manipulator (11) can be installed in other positions of wheel Wheel-chair car body (12) as required.
The driving of wheel Wheel-chair is to drive trailing wheel (15) realization by the electric wheel hub that is directly installed on the trailing wheel (15) by the wheel hub inner gear assembly, the pulse wide modulation mode is adopted in the speed governing of electric wheel hub, provide velocity of rotation and the direction that speed control signal is controlled electric wheel hub by manipulator (11), realize buffer starting, stepless speed regulation, the gradual braking of wheel Wheel-chair.Potentiometer formula Stellungsservosteuerung is adopted in the control that turns to of wheel Wheel-chair, the steering angle position feed back signal is detected by potentiometer (31), this feedback signal is controlled turning DC motor (33) with the given signal of wheel Wheel-chair steering angle and is rotated, steer motor (33) is rotated through the back shaft (34) that drive mechanism (32) drives trailing wheel, thus the corresponding steering angle of control trailing wheel (15).The transfer radius of turn is very little, but spins in the original place.
This utility model modern design drives and turns to the all-electric control of energy, and starting is steady with braking, but stepless speed regulation turns to sensitivity, and steering angle is very little, manoeuvrable, especially because adopted the mono-lever control mode, steering force is little, be applicable to the lower limb disable person and weak patient, old people, electronic and the manual dual-purpose of energy, price is suitable, and is reliable, easy to maintenance, be the ideal walking-replacing tool of patient, old people of the lower limb disable person and weak walking disorder.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is this utility model sketch map
Fig. 2 is a manipulator sketch map of the present utility model
Fig. 3 is driving device of the present utility model and transfer sketch map
Fig. 4 is a universal idle pulley elevating mechanism sketch map of the present utility model
Below in conjunction with accompanying drawing this utility model embodiment is further described: open the on and off switch (26) on the manipulator (11) before the use earlier, power supply indicator (22) on the manipulator panel (23) is bright, when battery voltage was not enough, the electric display lamp (24) of owing on the manipulator panel (23) can be bright.Stick (21) on the manipulator (11) mediates automatically at ordinary times, and the wheel Wheel-chair remains static.Work as front and back, about when promoting stick (21), two potentiometers that link to each other with stick (21) in the manipulator (11) can detect the position signalling of stick (21), a potentiometer detects the angle of passing before and after the stick (21), its output signal as the wheelchair Herba Plantaginis after the given control signal of the speed of service, another potentiometer detects the angle of passing about stick (21), its output signal is as the given control signal of wheel Wheel-chair steering angle, the highest running speed of wheel Wheel-chair can be set by the knob on the manipulator (25), and all control signals of manipulator (11) are sent into electric control system together.Electric control system accessory drive and transfer action, the wheel Wheel-chair is transferred to the running status of user requirement by resting state.
The elevating mechanism (16) of universal idle pulley (14) is equipped with at the rear portion of wheel Wheel-chair car body (12), during the wheel all-electric duty of Wheel-chair (I), trailing wheel (15) lands, universal idle pulley (14) is unsettled, support car body by trailing wheel (15) and two free front-wheels (13), when the wheel Wheel-chair need not electricity or during power driven system malfunction (II), operation elevating mechanism (16) can make universal idle pulley (14) land, trailing wheel (15) is unsettled, support car body by universal idle pulley (14) and two free front-wheels (13), the wheel Wheel-chair is by manual operation.
Claims (2)
1, a kind of all-electric life wheelchair car owner will be made up of car body, manipulator, driving device, transfer, electric control system, charging battery jar, it is characterized in that being equipped with on the car body (12) two free front-wheels (13) and a driving double trailing wheel that turns to (15), the manipulator (11) of mono-lever control mode is equipped with in the front portion of car body (12), and two universal idle pulleys (14) and elevating mechanism (16) thereof are equipped with in the rear portion of car body (12).
